We are accepting Bitcoin via BitPay, which I highly recommend as a BTC processor to anybody, as they work really good!
Bitcoin is actually very good. As processing fees are minimal. And risk of dispute is none.
Same as some other folks, we been sceptic about abuse of our services by clients who are using BTC. But, at least in our case, it turned out that compared to for example PayPal or CC, we had much lower amount of abusive clients who are using BTC as payment method. So in our case, this skepticism turned out as false.
So should you have Bitcoin as payment method? Yes!
Just be careful, as some banks don't like them. So always check with your commercial bank if they are ok with Bitcoin or not (this depends from country to country and bank policies as well).
